Answers & Explanations- Free and New GMAT Practice Test Sample Question 161-170

**161. D: The average daily cost may be written as 5.43+5.43+3.54+3.54+7.89/5, which equals 5.17. The average daily cost was $5.17.**

**162. C: When rounding the decimal to the nearest hundredths place, look to the digit that is one place to the right, or the thousandths place. Since the digit in the thousandths place is less than 5, the digit in the hundredths place will remain. Thus, the rounded number is 1230.93.**

**163. A: The decimals of 45.5 and 67.9 should be subtracted from the decimal, 134.7. Doing so gives a difference of 21.3.**

**164. B: The absolute value of a number is the distance the number is from 0. The integer, -9, is 9 units from the whole number, 0. Thus, it has an absolute value of 9.**

**165. D: Since this list (already written in ascending order) has an even number of values, the median is the average of the two middle values. The average of 7 and 9 is 8, thus the median is 8.**

**166. E: Since there are 52 weeks and 4 seasons in a year and 31 days in January, the average may be written as 52+4+31/3, which equals 29.**

**167. C: The GPA may be written as (4.4)3+(4.3)+(2.3)+(3.2)/13, where 13 represents the sum of the weights. Thus, the GPA is approximately 3.08.**

**168. A: The average is equal to the ratio of the amount spent to the number of days in a week. Thus, the average may be written as 28.49/7. He spent an average of $4.07 per day.**

**169. B: The rate may be written as 145-32/4, which equals 28.25. Thus, the average rise in temperature per hour was 28.25°.**

**170. A: The tenths place is one place to the right of the decimal. Thus, 2 represent the digit in the tenths place.**
